NoMethodError: undefined method `money_precision=' for #<Class:0x0000010321f788>

This is a fix for the invalid ticket: #5081 undefined method `money_precision=' for #<Class:0x105d7dda8> in postgresql_ad...

I also encountered this error, but only after installing the acts-as-tesearch plugin (http://code.google.com/p/acts-as-tsearch/) on OS-X.

$ rails c

NoMethodError: undefined method `money_precision=' for #<Class:0x00000102af3018>

I could fix this by changing line 937:

PostgreSQLColumn.money_precision = (postgresql_version >= 80300) ? 19 : 10

to

ActiveRecord::ConnectionAdapters::PostgreSQLColumn.money_precision = (postgresql_version >= 80300) ? 19 : 10

From what I could tell, this is because in the context, class PostgreSQLColumn is interpreted as a ActiveRecord::ConnectionAdapters::PostgreSQLAdapter::PostgreSQLColumn which as far as I can see is undeclared.
